PROBLEM TO BE SOLVED: To provide underground storage facilities of a waste geological disposal field which enables a drastic improvement in construction property in a waste recovery and in ease, safety, workability, etc. of the waste recovery by changing a facilities shape in the underground storage facilities of the geological disposal field for high-level radioactive waste, etc., and a recovery method of the waste. SOLUTION: In plural rows of disposal holes 3 excavated and formed in a first disposal tunnel 1 at intervals in a disposal tunnel longitudinal direction, a second disposal tunnel 2 is excavated and formed parallel to the first disposal tunnel 1. Two disposal tunnels 1, 2 of a parallel arrangement turn to a ladder type disposal panel connected by plural rows of disposal holes 3. The disposal tunnels 1, 2 are excavated and formed inclining the disposal holes 3 a little to a level by changing the depth of excavation. Only the downside disposal tunnel 2 is excavated to excavate and pull out a buffer material B from beneath and to pull out the waste C from beneath for recovery. COPYRIGHT: (C)2008,JPO&INPIT
